Actually, if memory serves, in the alternate universe created by Wanda in House of M, he was an agent of the (Wolverine run) S.H.I.E.D. He and Rogue were on the alpha squad headed by Mystique and Wolverine, and gosh if they all didn't make those uniforms look FINE.

Actually one of my favorite moments in that story arc was the look on Mystique's face when she realized this universe wasn't the true one; it was filled with so much regret, you could tell that accepting reality meant losing so many things she really wanted, a family unit, a place where she could use and challenge her skills, a surprisingly stable romantic relationship... I actually felt bad for her.

That was a tragic and amazing moment in the series for her. A few people say she never forgot that memory, hence her actions since. (Not sure I believe it but I can see where they think that).

I think he would be an incredibly effective agent of S.H.I.E.L.D. but I'd rather he start up a S.H.I.E.L.D. supernatural division with Doc Strange, Deadgirl (if she is truly coming back with other X-Statix members who are rumored to show up soon now that the Allred's are popular again), and maybe a few others. Ghost Rider? Blade? New Ghost Rider hasn't made a name for himself yet... best place to do that and get readership is put 'em on a team. Why make a mini? MAKE A WHOLE SERIES! You reading this Tom Brevoort?! YOU READING THIS?!
